You either charismatic or not.There is no such a thing of being found charismatic for a while.He is a top 3 player for the last 6 years he has an amazing 2011 followed by pretty good 2012,of course he will have some kind of fame and there will be some people who admires him.He is just doesnt have a star power like Borg and Agassi used to having,Fed and Nadal has.

Federer doesn't have any charisma. And all Nadal does is grunt and 'vamos' his butt off. You think anybody would care about these guys if they only had 2-3 Slams respectively?
